The Lineage of Project Management Methodologies
A century of process theory descends from two trunks: Taylor's plan-and-control school and the Deming and Toyota empirical school. Everything since, from waterfall to Scrum to SAFe, is mostly recombination. Hover any methodology to see exactly what it copied and who copied it.
How to read this: each pill is a methodology placed at its year of first appearance in one of three trunks. The curved links show who copied whom. Hover a methodology to light up everything it descends from (warm) and everything that descends from it (cool). Click to pin it and read the full story. Switch views with the tabs to recolor by trunk or era.
